This paper is concerned with the statistical behavior of oil prices in two ways. It, firstly, applies a combined jump GARCH in order to characterize the behavior of daily, weekly as well as monthly oil prices. Secondly, it relates its empirical results to implications of Hotelling-type resource...

This paper deals with three aspects of spectacular oil price episodes such as the one witnessed in 2008. First, the concept of temporary explosiveness is proposed as an empirical method for capturing this type of behavior. The application of a recently proposed recursive unit root test shows...

This paper finds that global temperature anomalies are characterised by (temporary) explosiveness, a statistical feature typically found in financial and commodity market data during episodes of extreme price increases. This finding dramatically illustrates the extent temperature changes have...

Mit diesem Beitrag beginnt eine Reihe im ifo Schnelldienst, die sich mit dem Klimawandel auseinandersetzt und aufschlussreiche Fakten dazu präsentiert. Illustriert werden diese durch Datenweltkarten. Begonnen wird diese Folge von Artikeln mit der Frage "Wie lange werden die Ressourcen reichen?"

This paper contributes to the green paradox literature by using a resource extraction framework with heterogeneous energy sources. A key feature of the model is a capacity constrained green backstop resource, which implies the simultaneous use of the expensive backstop resource and the cheaper...
